I want another betta fish...oh.. dear ... i'm addicted...
Does anyone know if 15 gallon tanks are fairly common? I don't really want to go as large as a 20 gallon and if I get another fish I will have 3. I think 5 gallons each would be plenty of room.

Does anyone know if petsmart or petco sell just a 15 gallon tank.. I don't need the hoodlight or filter, I already have the filter and I am planning on using 1 or two clamp lights for my plants.

I know I should just go look for myself, but I don't live near either store and I was just curious if anyone has ever seen one there?
